Yes! We think with our whole body, with the tools we use, with the space of the room we occupy, with the language we speak and write and wallow in, with the routines of work and of our daily lives, & when we walk down the street, with the shoes on our feet & the pavement beneath them & with everything we see & feel and hear in passing--with the trees we talk to, with the cat who lives with us! You see, MurphyCat! We make each other smarter! Oh, and Spirit Stick who walks with me! I knew that you had changed me, how I see myself, how I see the world!
